She served until the end of the war, during which she was noted for her courage and promoted to the rank of non-commissioned officer for bravery in battle.
After the war, she was employed for three years as head butler at the household of Countess Dücker, Hedvig Vilhelmina Oxenstierna (1682–1758).
Her daughter Margareta Charlotta Irving (1728-1765), married Nils Larsson Sundell (1692–1757), vicar at Bro parish in Västmanland.
[3][4] In contrast to other women serving in the army posing as men, including Ulrika Eleonora Stålhammar and Lisbetha Olsdotter, Margareta Elisabeth Roos was never discovered and brought to trial, and she is therefore not mentioned in any court documents, nor is the name which she used as a soldier known, which makes it hard to verify in military documents.
The fact that she married a man after service is also taken as an indicator that posing as a soldier did not lower the repute as a marriage candidate.
